Motion in a Straight Line
Three equationsv = u + ats = ut + ½at²v² = u² + 2as
Remember it Which equation? Ask what is missing: no s - the first; no v - the second; no t - the third.
Trap Average velocity uses displacement; average speed uses the whole distance.
Topper page
Motion in a Straight Line - in depth
Write it like this · Instantaneous velocity The limit of the average velocity as the time interval becomes very small, v = dx/dt - the slope of the tangent to the x-t graph at that instant. SI unit m s-1. NCERT Class 11 Physics Part I, Ch 2, §2.2
Twisted question A ball thrown up is momentarily at rest at the top. Is its acceleration zero there? No - its velocity is still changing; a = g downward even at the top.

How we keep it right
Checked before you read it
Every chapter starts from the NCERT textbook. Every question is solved again by two independent checkers who do not see the answer, every number is recomputed, every fact and page reference is checked against NCERT - and a final pass checks it all once more before it goes live. If you still find a mistake, the flag on every page and question sends it to us.
- Written from NCERTevery section, in order
- Checked twiceindependent checkers, answers hidden
- Final passdiagrams, explanations, a third check
- Report a mistakeon every page and question
